Four stars ... why not five?

A bit of principle! I do not know if a work of art must be perfect ... I like when she tells me, impresses me or moves me!
In a friendly group reading, a friend read us passages from the book, it reads very well, and it made me want to read it again.
Reading is a delight, the story, the characters are strong, the novel is not dense and long.
What struck me this time is the staging of the power of human genius unstoppable! This gave me optimism in these times of doubt and disorder.
